Description

Technical Field

[0001] This invention relates to the field of density detection technology, specifically to a monitoring device for the saturation of grouting in backfill areas of mines. Background Technology

[0002] The sleeve grouting fullness monitoring equipment is a specialized device used in the grouting construction of steel sleeves in prefabricated buildings to monitor whether the grout material is fully filling the inside of the sleeve. In actual construction, conventional sleeve grouting fullness monitoring equipment generally suffers from insufficient monitoring accuracy. Due to the complex internal structure of the sleeve, the flow state of the grout material is difficult to judge intuitively, and the equipment cannot accurately capture the degree of grout filling inside the sleeve. This can easily lead to insufficient steel reinforcement connection strength due to incomplete grouting, seriously affecting the structural safety of prefabricated buildings.

[0003] Publication number CN221377984U describes a fiber optic-based continuous beam duct grouting fullness monitoring device. This device uses a motor-driven transmission mechanism to rotate, which in turn moves a transmission rod via a connecting shaft. The transmission rod, through a toothed column, rotates a lead screw, which in turn moves a protective shell via a moving rod. This allows the device to be adjusted according to different monitoring depths, solving the problem that traditional monitoring devices cannot be adjusted for different operating environments.

[0004] However, the above-mentioned technical solutions based on fiber optic channel monitoring structures cannot be adapted to the narrow space and special structure of sleeves. Furthermore, the method of making depth adjustments through motors, transmission mechanisms, etc., is too complex and cumbersome to meet the small-scale, high-precision monitoring requirements of sleeve grouting. It cannot quickly and accurately monitor the fullness of the grouting material inside the sleeve, which will still lead to inaccurate monitoring results.

[0005] Therefore, in order to address the existing shortcomings, we conducted research and improvements and proposed a monitoring device for the grouting fullness of the mine pit backfill area. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes the collaborative operation of components such as the expander, guide rod, rotating blade, and fan blade. When the slurry impacts the expander, it drives the guide rod and side push bar to rotate the rotating blade, which in turn drives the fan blade to rotate inside the arc opening. The arc plate at the bottom of the fan blade is screwed and engaged with the external texture of the slurry inlet. Combined with the buffering effect of the stress ring and the fourth spring, the sleeve and slurry inlet structure remain stable, ensuring that the equipment does not shake when a large amount of slurry flows in, can withstand a large slurry impact force, and guarantees the stability of the monitoring process. 2. This invention uses fan blades to drive the force-bearing rod, rotating ring, and lever in a coordinated manner, which in turn drives the rotating plate, force-bearing rod, and cam to rotate. This causes the rocker arm to move the blocking rod upward, opening the channel of the rigid pipe. After the grout enters the rigid pipe, it pushes the second round plug, liquid rod, and sliding plate upward. The slider slides along the matching strip, and the top of the sliding plate aligns with the designated position of the scale groove. This allows workers to quickly obtain grout inflow intensity data, providing a direct basis for judging the grout fullness and improving the convenience of monitoring data acquisition. 3. This invention uses an upward-moving slider to move the push rod and the first shifting plate, causing the expansion and contraction bladder to extend and wrap around the float rod. Simultaneously, it moves the second shifting plate, the front plate, and the deformed block upwards, releasing the pull-down plate from fixing the bottom of the sleeve. After grouting is completed, the deformed block resets and locks the pull-down plate, keeping the sleeve in a fixed position. This prevents rotation or loosening due to grout impact or vibration, ensuring the stability of the equipment installation position and improving the accuracy of monitoring results.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: like Figures 1 to 19 As shown, a grouting fullness monitoring device for backfill area of ​​a mine pit includes: a sleeve 1, a grout inlet 22 at one end of the sleeve 1, a scale groove 29 on the front of the sleeve 1, a vertically arranged jacking rod float 6 in the cavity inside the sleeve 1, a connecting rod 27 at the bottom of the jacking rod float 6, a first round plug 28 at the bottom of the connecting rod 27, and a first spring 26 sleeved between the outside of the connecting rod 27 and the top of the inner side of the sleeve 1. A stress-relieving ring 50 is fitted at the connection between one end of the sleeve 1 and the slurry inlet 22. A jacket 51 is symmetrically arranged on both sides of the front of the stress-relieving ring 50. A sliding shaft 52 is transversely arranged on the inner side of the jacket 51. A fourth spring 49 is fitted at the rear end of the outer side of the sliding shaft 52. The front end of the stress-relieving ring 50 is provided with a stabilizing mechanism, which includes an expanding arc frame 2, which is located at the front end of the stress-relieving ring 50. The sleeve 1 has a vertically arranged adapter shell 5 on its front side. The inner side of the adapter shell 5 is attached to the front side of the sleeve 1 and has an indicator mechanism. The indicator mechanism includes a locking strip 20 and an upper locking ring 30. The locking strip 20 is arranged on both sides of the front side of the sleeve 1 near the adapter shell 5. The upper locking ring 30 is arranged on the top of the locking strip 20. The float 6 is provided with a retrieval mechanism on its exterior, which includes a retractable bladder 15, which is located on the exterior of the float 6. When the adapter shell 5 and sleeve 1 are buried in the backfill area of ​​the mine pit, the stress relief ring 50 is also buried. When a large amount of slurry flows into the backfill area of ​​the mine pit, the slurry impacts the stress relief ring 50. The stress relief ring 50 is forced to move the outer sleeve 51 outside the sliding shaft 52. At the same time, the fourth spring 49 can slow down the speed and distance of the movement of the outer sleeve 51. This ensures that the sleeve 1 will not shake due to the influx of slurry when its position is adjusted. The slurry enters the interior of the sleeve 1 through the slurry inlet 22. After the slurry fills the interior of the sleeve 1, it pushes the first round plug 28 to rise. When the first round plug 28 rises, it drives the connecting rod 27 to move. When the connecting rod 27 moves upward, it can drive the float 6 to protrude from the interior of the sleeve 1. At the same time, the first spring 26 can help the first round plug 28 to reset when the slurry is insufficient.

[0022] Example 1: As Figures 1 to 19 As shown, the stabilizing mechanism also includes an expansion plate 4, a cover 21, a guide rod 23, a guide plate 24, a horizontal opening 25, a second spring 31, a vertical shaft 32, a fan blade 33, a side push bar 34, a rotating plate 35, and an arc opening 36. A vertical rectangular portion is provided at the middle of the upper part of the front of the expanded arc frame 2, with a hole penetrating its upper end. An arc opening 36 is provided on one side of the inner side of the expanded arc frame 2, and a fan blade 33 is obliquely penetrating through the inner side of the arc opening 36. A blade 35 is provided at the lower end of one side of the blade 33. A vertical shaft 32 is provided at one end of the bottom of the blade 35. A side pusher 34 is provided on one side of the front of the blade 35. A guide rod 23 is provided at the front end of the blade 35. A guide plate 24 is provided on one side of the front end of the guide rod 23. A side pusher 34 is provided on one side of the guide plate 24. An expansion plate 4 is provided on the other side of the guide plate 24. A cover 21 is provided on the front of the expansion arc frame 2. A horizontal opening 25 is provided through the front of the cover 21. The expanded plate 4 is composed of a combination plate and an arc plate with a right angle, and the expanded arc frame 2 is composed of four sector shells containing cavities; The rigidity of the guide rod 23 is less than that of the rotary plate 35, and the guide rod 23 and the rotary plate 35 are an integrated structure. The rotary plate 35 has a Z-shaped structure, the guide rod 23 has a flat rectangular structure, the rigidity of the side push bar 34 is greater than that of the guide plate 24, and the side push bar 34 and the guide plate 24 are an integrated structure. The guide rod 23 can move horizontally along the horizontal edge of the transverse opening 25. The upper end of the fan blade 33 is a fan-shaped part, and the lower end of the fan blade 33 that is attached to the slurry inlet 22 is an arc plate part. The entire fan blade 33 can move along the ridge line of the arc opening 36. When a large amount of slurry impacts the slurry inlet 22, the inner side of the expander 4 is subjected to force and expands outward. The expander 4 can drive the guide plate 24 and the guide rod 23 to move. The guide rod 23 can drive the side push bar 34 to move to one side inside the enlarged arc frame 2. The rotating blade 35 can be pushed by the side push bar 34 to rotate. The rotating blade 35 can rotate at the top of the vertical shaft 32. When the rotating blade 35 rotates, it pushes the fan blade 33 to rotate. At this time, the bottom of the fan blade 33 rotates inside the arc opening 36, and the arc plate part at the bottom of the fan blade 33 can slide on the surface of the slurry inlet 22. Since the arc plate part of the fan blade 33 can be screwed and locked with the texture on the outside of the slurry inlet 22, the structure between the sleeve 1 and the slurry inlet 22 will remain stable, and the slurry inlet 22 and the sleeve 1 can withstand the influx of a large amount of slurry.

[0023] Example 2: Figures 1 to 19 As shown, the indicating mechanism also includes a rigid tube 3, a rocker arm 10, a lifting plate 11, a switch head 12, a rotating rod 13, a force-receiving rod 37, a rotating ring 38, a large rotating plate 39, a lever 40, a retaining ring 41, a cam 42, a force-receiving rod 43, a rotating plate 44, a positioning bar 45, a third spring 46, a slider 47, a sliding plate 48, a top cover 53, a second round plug 54, a fifth spring 55, a blocking rod 56, a cavity plug 57, a sixth spring 58, and a hydraulic rod 59. A rigid tube 3 is installed inside the locking strip 20. A top cover 53 is fixedly installed at the upper end of the inner side of the rigid tube 3. A hydraulic rod 59 is vertically inserted through the inner side of the top cover 53. A second round plug 54 is installed at the bottom of the hydraulic rod 59. A fifth spring 55 is installed at the top of the second round plug 54. A sliding plate 48 is installed at the top of the hydraulic rod 59. Slider arms 47 are installed on both sides of the sliding plate 48. A switch is installed in the middle of the top of the rigid tube 3. The switch head 12 has a vertically arranged blocking rod 56 on its inner side. A lifting plate 11 is arranged on the top of the blocking rod 56. A sixth spring 58 is sleeved on the lower end of the blocking rod 56. A cavity plug 57 is arranged at the bottom of the blocking rod 56. A rocker arm 10 is arranged at the bottom edge of the lifting plate 11. Rotating rods 13 are arranged on both sides of one end of the rocker arm 10. A cam 42 is arranged at the other end of the bottom of the rocker arm 10. A rotating force rod 43 is arranged on the front of the cam 42. A rotating receiving plate 44 is arranged at one end of the rotating force rod 43. A positioning strip 45 is arranged at the rear end of the rotating receiving plate 44. A third spring 46 is arranged on the outside of the rotating receiving plate 44. A retaining ring 41 is sleeved on the outside of the third spring 46. A lever 40 is arranged on one side of the outside of the rotating receiving plate 44. A large rotating plate 39 is arranged at one end of the lever 40. A rotating ring 38 is arranged at the bottom of the large rotating plate 39. A force rod 37 is arranged at one end of the front of the rotating ring 38. The rotating ring 38 can rotate around the outside of the slurry inlet 22. The length of the force rod 37 is equal to the length of the arc plate part at the bottom of the fan blade 33. The retaining ring 41 is installed inside the hole of the vertical rectangular part of the extended arc frame 2. The rotating plate 44 and the positioning strip 45 form a rotational motion. The rotating rod 13 and the rocker arm 10 form a rotating structure, and the slider 47 and the card strip 20 form a vertical sliding structure; When the arc plate part of the fan blade 33 rotates outside the slurry inlet 22, the arc plate part will push the force rod 37 to move, the force rod 37 will drive the rotating ring 38 to rotate outside the slurry inlet 22, the rotating ring 38 will drive the large rotating plate 39 to rotate, and the large rotating plate 39 will drive the lever 40 to rotate. When the lever 40 rotates, it can push the rotating plate 44 to rotate inside the retaining ring 41. The third spring 46 can help the rotating plate 44 to reset after losing power. When the rotating plate 44 rotates, it can drive the rotating rod 43 to rotate. When the rotating rod 43 rotates, it will drive the cam 42 to rotate. After the cam 42 rotates, it will squeeze the rocker arm 10 to rotate downward. Note that at this time, the cam 42 is moving around one end of the rocker arm 10. In addition, the rotating rods 13 on both sides of the rocker arm 10 can help it rotate. After the rocker arm 10 rotates downward, one end of the rocker arm 10 lifts the lifting plate 11 and moves it upward. The lifting plate 11 drives the blocking rod 56 to move upward inside the switch head 12. After the blocking rod 56 moves upward, it will drive the cavity plug 57 to move upward. At this time, the channel inside the rigid tube 3 will be kept unobstructed, and the sixth spring 58 can help the blocking rod 56 to reset after losing power. Furthermore, since one end of the rigid tube 3 can simultaneously draw in the incoming slurry at the slurry inlet 22, but the rigid tube 3 can only draw in a portion of the slurry, the slurry inside the rigid tube 3 will impact the second plug 54. The second plug 54 will be pushed upwards, and the second plug 54 will drive the liquid rod 59 to move upwards inside the top cover 53. The fifth spring 55 can help the second plug 54 reset after losing power. When the liquid rod 59 moves upwards, it can push the slide 48 upwards. The sliders 47 on both sides of the slide 48 can slide outside the card strip 20. When the slide 48 moves, the edge of the top of the slide 48 can move to the designated position of the scale groove 29, so as to help the staff quickly know the intensity of the slurry inflow.

[0024] Example 3: Figures 1 to 19As shown, the taking mechanism also includes a digging plate 7, a downward rotating clamp 8, a pull-down plate 9, a first shifting plate 14, a front plate 16, a second shifting plate 17, a push rod 18, and a deformed block 19. The second shifting plate 17 is provided on one side of the upper end of the expansion and contraction bladder 15, the front plate 16 is provided at the bottom of the second shifting plate 17, and the deformed block 19 is provided on the surface of the front plate 16. The lower end of the outer side of the downward rotating clamp 8 is provided with a downward rotating clamp 8, and the pull-down plate 9 is rotatably provided on the inner side of the downward rotating clamp 8. The first shifting plate 14 is provided on the other side of the upper end of the expansion and contraction bladder 15, and the push rod 18 is provided on the top of the first shifting plate 14. The cross-sectional structure of the deformed block 19 is a triangular convex structure, and the geometric centers of the first displacement piece 14 and the second displacement piece 17 are on the same straight line. When the slider 48 moves upward, it drives the push rod 18 to move upward. The push rod 18 drives the first shift plate 14 to move. When the first shift plate 14 moves, it drives the expansion and contraction bladder 15 to extend outside the float 6. At this time, the expansion and contraction bladder 15 gradually wraps around the float 6. When the expansion and contraction bladder 15 gradually moves upward, it drives the second shift plate 17 to move. The second shift plate 17 drives the front plate 16 to move upward. The front plate 16 drives the deformed block 19 to move upward. As the deformed block 19 moves upward, it gradually moves away from the pull-down tab 9. At this time, the pull-down tab 9 rotates slightly inside the lower screw clip 8. The bottom part of the pull-down tab 9 will move away from the bottom of the sleeve 1. When the expansion and contraction bladder 15 does not move upward, the deformed block 19 is stuck inside the upper end of the pull-down tab 9, so that the pull-down tab 9 abuts against the bottom of the sleeve 1, thereby keeping the sleeve 1 in a fixed position when receiving the incoming propeller, and preventing it from rotating or loosening due to propeller impact or other vibrations.
